Abstract

A display device includes a display panel and a housing capable of accommodating the display panel. The display panel includes a first display region and a second display region and is flexible. Display in the first display region and display in the second display region are visually recognizable in a first direction in a state where the display panel is taken out from the housing. The display in the second display region is visually recognizable in a second direction opposite to the first direction in a state where the display panel is accommodated in the housing.

Claims (54)

1. A display device, comprising:

a display panel including a first display region and a second display region, the display panel being flexible; and

a housing capable of accommodating the display panel,

wherein

display in the first display region and display in the second display region are visually recognizable in a first direction in a state where the display panel is taken out from the housing, and

the display in the second display region is visually recognizable in a second direction opposite to the first direction in a state where the display panel is accommodated in the housing,

wherein

the first display region includes a first light emitting element,

the first light emitting element includes a light-reflective pixel electrode, a first organic layer and a light-transmissive counter electrode,

the second display region includes a second light emitting element, and

the second light emitting element includes a light-transmissive pixel electrode, a second organic layer and the light-transmissive counter electrode.

2. The display device according to claim 1 , further comprising:

a first polarization plate provided above the second display region, and

a second polarization plate provided below the second display region,

wherein the first polarization plate and the second polarization plate are provided in a crossed-Nicols state.

3. The display device according to claim 1 , further comprising a third polarization plate provided above the first display region.

4. The display device according to claim 1 , further comprising a touch panel provided below the second display region.

5. The display device according to claim 1 , further comprising a touch panel provided above the first display region and the second display region.

6. A display device, comprising:

a display panel including a first display region and a second display region, the display panel being flexible; and

a cylindrical housing capable of accommodating the display panel,

wherein

the cylindrical housing has an opening, and

display in the second display region is visually recognizable through the opening in a state where the display panel is accommodated in the cylindrical housing.

7. The display device according to claim 6 , further comprising:

a first polarization plate provided above the second display region, and

a second polarization plate provided below the second display region,

wherein the first polarization plate and the second polarization plate are provided in a crossed-Nicols state.

8. The display device according to claim 6 , further comprising a third polarization plate provided above the first display region.

9. The display device according to claim 6 , further comprising a touch panel provided below the second display region.

10. The display device according to claim 6 , further comprising a touch panel provided above the first display region and the second display region.

11. The display device according to claim 6 , wherein

the first display region includes a first light emitting element,

the first light emitting element includes a light-reflective pixel electrode, a first organic layer and a light-transmissive counter electrode,

the second display region includes a second light emitting element, and

the second light emitting element includes a light-transmissive pixel electrode, a second organic layer and the light-transmissive counter electrode.

12. A display device, comprising:

a display panel including a first display region and a second display region, the display panel being flexible; and

a foldable housing accommodating the display panel,

wherein

the housing has an opening, and

display in the second display region is visually recognizable through the opening in a state where the housing is folded,

wherein

the first display region includes a first light emitting element,

the first light emitting element includes a light-reflective pixel electrode, a first organic layer and a light-transmissive counter electrode,

the second display region includes a second light emitting element, and

the second light emitting element includes a light-transmissive pixel electrode, a second organic layer and the light-transmissive counter electrode.

13. The display device according to claim 12 , further comprising:

a first polarization plate provided above the second display region, and

a second polarization plate provided below the second display region,

wherein the first polarization plate and the second polarization plate are provided in a crossed-Nicols state.

14. The display device according to claim 12 , further comprising a third polarization plate provided above the first display region.

15. The display device according to claim 12 , further comprising a touch panel provided below the second display region.

16. The display device according to claim 12 , further comprising a touch panel provided above the first display region and the second display region.
